Well one thing I can tell you is that it's out of a '95 UZS151 Crown Majesta but can't help with a wiring diagram though
If you have the plug for the 28P socket it will have the tails of the wiring on it. Looking at the side that the wiring is on start from the top right which is pin one go from right to left numbering each wire and note the colours. Post up the results and some of us might be able to shed some light on the subject so you can make it go. It will take a lot of time but joys of these conversions
